Topic: Capistrano hangs after update_code-- why?

On cap deploy, capistrano is hanging after checking out from the svn repo in the update_code task (svn+ssh).  I've verified that the code is updated, but capistrano hangs without any further action or message --- there's no acknoledgement that update_code is complete and no further action on the symlink task.

This seems to happen on medium to large size deployments. Is there some sort of timeout issue?  Thanks for any ideas -- this is turning out to be a big problem.
